Which waveform represents Vo in the shown circuit driven by Vs=2sin(2πt) V? The Zener breakdown voltage is 1 V and its forward voltage is idealized to zero.
The diode orientation clips the positive part at its one-volt reverse-breakdown level and conducts ideally on the opposite polarity, clamping the negative output to zero. Thus the output follows the positive sine only below one volt, clips at one, and is zero during the negative half-cycle. This is C.
